try disabling all plugins first to see if there is a conflict.
To do this without access to the admin dashboard you will need to access your site via FTP / host file editor. Navigate to the Plugin directory and rename each of the plugin folders.
I am unable to log in to my wordpress dash board, and i am a novice and if someone can help that will be great. I am only okay with the dashboard way. I dont want to ruin anything.
Just need help to restore my website and roll back to the earlier GP theme version
